Question

what happens during hemostasis? selective all that apply. A cascade of events leads to clot formation, fibrin clot formation, hemorrhage, clot dissolution, removal of the clot by hemoglobin

Answer 1

Answer:

A cascade of events leads to clot formation & fibrin clot formation

Hemostasis is a process in which blood loss from body will be prevented through the closing of ruptured blood vessel.

Hemostasis mechanism will be divided into four stages:

1. Vasoconstriction: Constriction of the blood vessel / vascular spasm will occur when wall of the vessel is damaged
2. Platelet plug: Formation of a temporary “platelet plug" by platelet combining together with exposed collagen and endothelial lining
3. Activation of the coagulation cascade: Intrinsic and extrinsic coagulation originated and meets at a specific point, leading to fibrin activation
4. Fibrin plug: Formation of “fibrin plug” or the final clot will be formed by the action of protease thrombin on fibrinogen.
